AT&T and Metro North Testing Wifi?

I spotted a new hotspot while waiting to depart from Grand Central tonight …

Unfortunately, I was unable to connect from my iPhone or laptop, but signal was pretty decent for a few fleeting moments regardless. I really hope that this is an active test and that wifi starts to rollout. Currently there is wifi along the train line via Cablevision, Time Warner and Comcast though it’s impossible to actually use on the go.

I obviously have no helpful information on this possible test, but can say I’d be very interested in using it and would even pay. AT&T is looking to glean an extra $45/mo for tethering and while that would be bandwidth I could use all to myself, a slightly slower shared connection would be of great use. I tend to use the iPad rather than my laptop, but there are plenty of times when the laptop would be handy …

I wonder if Metro North is serious with this and even if they’d consider free. For pay, I’d love to see it packaged or validated with a monthly rail pass.
